And then what? Environmental architecture feng shui is also divided into yin and yang, which is how feng shui is defined. Buildings living in human settlements are collectively referred to as yangzhai, and buildings that provide shelter for the dead, such as cemeteries, graves, urns and other buildings related to the dead, belong to yinzhai. The word feng shui can be interpreted in two ways. One is in a broad sense, referring to the nearby natural environment such as space, mountains, water and trees. For example, the feng shui here is really good. It is really a treasure trove of feng shui. One is narrow sense, especially yin house (ancestral grave) and yang house (housing).
